. COOKING Application filed April 'Z,

To all whom it may concern.

Be'it known that we, HAROLD V. MUL- ronn and WALTER D. FELTY,'ci-tizens of the United States, residing at Paulsboro, in the county of Gloucester and State of New Jersey, have invented new and useful "Improvements in Cooking Utensils, of which the following is a specification. i This invention relates to cooking utensils and it has more particular reference to that type Or form of utensil which is provlded with means" for preventing the boiling over of liquid therefrom, the primary object of our invention being to provide anovelform of cooking utensil which when in use prevents scorching," burning,- or over-boiling of its contents. 1

Another object of our invention isthe provision of a cooking utensil of the fore going referred to character which greatly facilitates the cooking of comestibles and the like Without appreciable loss of'any of their nutritive qualities.

Further objects attained by this inventlon are the provision of a cooking utensil which is simple iii-construction, cheap to manufacture. eflicient in use, and free from the disadvantages inhering to general constructions at present in vogue, the'same being adversely affected by expansion and contrac tion which frequently results in'the separation of the co-related parts.

lVith these and other objects in view our invention essentially consists in certain novel features of construction, combinations and arrangements of parts hereinafter fully described andmore' particularly defined by the appended claims;

In the further disclosure of the invention reference is to be hadto the accompanying sheet of-e xplanatory drawings constitutlnga part of this specification and in which like characters of reference designate the same or corresponding parts in, all the views.

Figure 1' is a sectional elevation through embodying our improvements. Figure 2Y is a top'plan' viewofthe "same with parts'hr'oken' away or section to disclose the underlying, structure; and,

Figure 3 is a detail plan to an enlarged scale ofa float valve hereinafter more fully described. c r

Referring more particularly to the v ews the numeral 4 designates a'pa'n or Vessel of a propriate material preferably alum1num' urnusin.

which is moulded. 01 fashioned about its i tached to the aforesaid ,pan or vessel/1 as by rivets 7 is a handle'8of concavo-convex cross section, the outer end whereof is shaped as shown at-9 to constitute a comfortable hand-hold, while a hole or slot 10 is punched therethrough'to provide a means whereby'the utensil may be hung up when not in use. I J

Adapted for snug fitment to the bottom 11 of the aforesaid panor vessel 4 is an extension or false bottom 12, the same being provided about itsvertical wall 13 with a series of inwardly directed tongues 14 ap propriately stamped "out :therefrom, i said tongues serving as a seat or support" for the bottom ll of the aforesaid pan or vessel 4:.

In order to immovably lock the extension or false bottom 12 to the pan or vessel 4'we provide a seriesof inwardly directed indents 15 about the lower portion of said pan or vessel 4 into which are forced or sprung correspondingly shaped and inwardly directed tits 16' provided about theperimeter or vertical wall 13 of'the falsebottom-12 and it will be readilyunderstood by those acquainted withthe sheet metal industry that by this means we have furnished an effective manner of securely supporting and connecting together in roper relation the pan or vessel 4: and the false bottom 12;

An important feature to be particularly noted at this point is that we have found by actual experiments in connection with cooking utensils of analogous or-like nature to the one forming the subject matter of our present invention that where the same have beenprovided with a falseqbottom it has usually been the practice to make such false bottom of a different kind of heat resisting material to that of the pan "or Vessel portion. As a result of these tests we have evolved the means just described for supporting and locking the false bottom l2 to the pan or vessel L, and furthermore we make said false bottom 12 of the sam'efm'aterial-'prefe'rably aluminum-as the pan or vessel 4 so that the ratio "of' expansion and contraction is the same inbothport ions. In other" words, cooking utensils of the nature andcharacter hereinbefore referred to have heretofore been proven somewhat-objectionable in use, due to the different character and heat resisting qualities of the false bottom relative to the pan or vessel portion it frequently obtaining that when a cooking utensil has been removed from the fire and placed on the side to cool that the pan or vessel portion has become easily detached. from the false bottom portion thereby resulting in much inconvenience when using utensils of the nature set forth.

The aforesaid false bottom 12 is prefer ably made of the cross section shown in Figure 1, that is to say, it is curved inwardly around its basal portion 17 into somewhat U-shaped cross section, whilst the inner portion of the bottom 18 is fashioned or spun with a series of stepped corrugations 19, the central portion thereof being upwardly dished as shown at 20. In order to permit the free entry for circulation of air ,or liquid into the space intervening the bottom 18 and the vessel or pan bottom 11, the false bottom is provided with a series of perforations or holes 21 therethrough.

Adapted to seat in the hereinbefore referred to shoulder or expandedpart 5 is a lid or cover 22, the central portion 23 whereof is somewhat funnel-shaped and provided with an axial aperture 2 1 therethrough. Around the flat or upper portion of the lid 22 we provide a series of perforations 25 for a purpose later on explained. Supported beneath the central part of the funnelshaped portion 23 of said lid 22 is what may be termed a basket or carrier 26 preferablyof the cross section clearly shown in Figure 1, and it is to be noted that this basket 26 is looked 011 the underside of the funnel-shaped portion 23 by means of depending t'ongues 27'stamped out therefrom engaging beneath the peripheral flange 28 of the basket 26.

It will be readily understood from an inspection of Figure 2 that the peripheral flange 28 of the basket 26 is provided with a notched out part 29 and those acquainted with the art will readily understand that by the provision of said notched out part 29 an easy and simple means is provided whereby the said basket can be removably engaged beneath the funnel-shaped part 23, it being obvious that when the flange part 28 is slipped beneath two of the depending tongues 27 with the notched part 29 in register with the third one by slightly turning said basket it may be removably locked beneath the lid or cover 22.

Disposed within the basket 26 is a float or valve member 30 shown to an enlarged scale in Figure 3. This float is provided with a plurality of radial arms 81 between which are intervening spaces 32 and it will be readily understood by those acquainted with the art that this float or valve 30 is adapted to rise and fall within the basket. On an examination of Figure 1 more particularly it will be seen that when the float or valve 30 rises the central portion thereof will serve to close the aperture 24 in the lid 22 and this float or valve 30 serves in use to prevent overboiling through the said central aperture 24 as later on explained. Appropriately formed at the frontal portion of the pan or vessel, and in the expanded or shouldered part 5 we form an inwardly directed arcuate rib 33 as clearly shown in Figure 2 of the drawings, and beneath this rib 33 the frontal partof the lid or cover 22 is adapted to be projected and snugly engaged. At the back portion of the lid we attach as by rivets 34 a handle 35 which is of the-cross section clearly shown in Fig- I ure 1, that is to say, it is upwardly curved to pass over the spun bead 6 of the pan or vessel 4 and shaped to lie in neat spaced relation relative to the panhandleS. In order to provide an effective means for looking the lid or cover 22 in position in the expanded or shouldered part 5, we stamp out from the handle 35 a downwardly depending tongue 36, the free end whereof is rolled or turned at 37 so as to constitute a spring gripping device for engagement over the edge and slightly under the aforesaid bead 6, and it will be readily understood that by the engagement ofthe lid 22 beneath the arcuate bead 33 and the locking of the spring tongue 37. In engagement on the bead 6 an effective and novel means is provided for holding the said lidor cover in place; Still further the same. is. of a nature and character which lends itself. to ease and facility in use in that there is. no necessity to swing the lid or cover. about its axis to effect a locking engagement in the pan or vessel, the same being, perfectly obvious to those acquainted with the art that the most inexperienced person will readily see the manner of placing the lid inthe pan which will result in its prompt and easy locking.

From the foregoing descriptionand an examination of the drawings it will .be readily seen that when a panor cooking utensil embodying our improvements is placed over a flame or fire the heat will be directed evenly over the false bottom 12 due to the peculiar undulating formation of the inner false bottom 18. This distribution of the heat results in the major portion thereof being, directed have shown and described a preferred form; or embodimentiof our 1n'vent1on,we do not 11 of the pan or vessel 4 causes a distribution of heat which will be found very effective for the purposes desired. We are fully aware that cooking utensils of analogous nature have been heretofore made,used and vended, and we lay no claimiwhatsoever to such an article per se, that is to say, we donot desire it to be understood that we claim a non-boil-over cooking utensil, but what we do desire to be clearly understood is 'that by. our invention and novel features of construction, we have produced a cooking utensil possessing many advantages over those heretofore in use and wewjish to lay particular emphasis upon the peculiar formationof the float or valve member 80andits disposition relative to the cover or lid 22. By its peculiar formation it will be readily seen that it will promptly closethe central aperture 24 when boiling commences within the pan or vessel 4, but on the otherhand itwill not impede the returnhof any condensation or liquid boiling up through the perforations 25jfro'mdraining down andpassing through the central aperture 24 andbasket 26back into thepan-or vessel 4.

From the foregoing description itiwill. be

readily seen that by our inventionwe have made an advancein the art and the numerous advantages accruing to our,improve--- ments'in cooking utensils offthe character described will be self-evident without further explanation or description. While we desire tobe exclusively restricted thereto in that it will be apparent slight detail changes may be effected without departing from the spirit and nature of the-said invention as more particularly defined byv the appended claims.
